Lesson 5.1 Lists explore

Overview

Students will learn the ways that lists are created, accessed, and changed through a teacher-guided activity using plastic baggies and pieces of paper. The lesson begins with a brief reflection on the value of lists. Students then complete the main activity which introduces the syntax to use lists and the ways they can be used. To wrap up students watch two short videos on lists and record the main concepts in their journals.

Purpose

In the warmup, students brainstorm different lists of information that they encounter on a daily basis. Then in the activity, students return to baggies and sticky notes from the previous unit to build a concrete model of a list before seeing how lists are programmed in Javascript. Students are exposed to different ways of interacting with a list like accessing, removing, appending, and inserting elements. The wrap up concludes the lesson with a summary video and a journal vocabulary exercise.

Standards

CSP Conceptual Framework

• AAP-1 - To find specific solutions to generalizable problems, programmers represent and organize data in multiple ways.

• AAP-2 - The way statements are sequenced and combined in a program determines the computed result. Programs incorporate iteration and selection constructs to represent repetition and make decisions to handle varied input values.

CSTA K-12 Computer Science Standards (2017)

AP - Algorithms & Programming

• 3A-AP-14 - Use lists to simplify solutions, generalizing computational problems instead of repeated use of simple variables.
